The most recent opportunity to meet us and discuss the new didactic concept with us was at the following conference:
- ChemEd Conference 2023, July 23-27, 2023, Guelph / Canada (oral presentation (with experiments) “Electrochemistry—A Question of Potential” and workshop ““Mysteries” of Surface Phenomena”).
August 2023
The PowerPoint presentation to the lecture “Electrochemistry―A Question of Potential” is published under Teaching Materials/Presentations. The workshop comprises four experiments such as the Daniell cell and the homemade Voltaic Pile that represent an ideal first experimental step into the topic.

ChemEd Conference 2023 from 23th to 27th July 2023 in Guelph / Canada
At the conference, Dr. Regina Rüffler gave the 45 minute oral presentation “Electrochemistry―A Question of Potential” with four interesting experiments (such as the “Homemade Voltaic Pile”). The lecture aroused great interest.
Additionally, she presented the workshop ““Mysteries” of Surface Phenomena”. After a short theoretical introduction into the topic, the attendees had the opportunity to carry out amazing hands-on experiments at seven stations according to the rotation model.
Finally, she took part in the “Mole Storytelling Event” during the closing ceremony.
March 2023
The PowerPoint presentation to the workshop “The “Mysteries” of Surface Phenomena” is published under Teaching Materials/Presentations. The workshop comprises seven experiments that are particularly suitable to illustrate different aspects of surface phenomena.

26th IUPAC International Conference on Chemistry Education 2022 from 18th to 22th July 2022 in Cape Town /South Africa
At the conference Dr. Regina Rüffler gave the lecture “Genie of Catalysis” with five fascinating experiments on the topic of catalysis (such as the “Dancing Absinthe”) presented as videos (for logistical reasons).
Additionally, she offered the brand-new 90-minute workshop “The “Mysteries” of Surface Phenomena”. After a short theoretical introduction into the topic, the attendees had the opportunity to carry out interesting hands-on experiments at seven stations according to the rotation model.
June 2021
Ten new instructions to demonstration experiments, primarily concerning the topics of “Behavior of Gases” (10.1, 11.1), “Indirect Mass Action” (12.1, 12.3 and 12.5) as well as “Interfacial Phenomena” (15.2, 15.3 and 15.5), were published under Teaching Materials/Demonstration Experiments.
Have fun with the experiments in your lab and the lecture hall! I especially like the so-called “gas law apparatus,“ one of the nice experiments I was able to purchase with the prize money for the “So You Think You Can Demo” contest. With the help of this apparatus, it is very easy to demonstrate quantitatively the relationship between pressure and volume of a constant amount of gas. The apparatus is also small enough to be passed around as hands-on experiment.
March 2021
The 112th MNU Congress (Annual Meeting of the German Association for the Advancement of Teaching in Mathematics and Natural Sciences) took place online for the first time in its history from March 4 to 6. Dr. Rüffler presented the workshop “Teaching Entropy with Fun” where actually the attendees were supposed to perform seven experiments that are particularly suitable to illustrate different aspects of entropy at various stations according to the rotation model. This was unfortunately not possible because of the Corona pandemic, but at least the attendees could do two experiments with everyday objects in front of their screen. There were many encouraging comments of the attendees thanking for the informative lecture and the many experimental suggestions, but I nevertheless hope very much that the next congress will be face-to-face again. However, I took this presentation as an opportunity to put together a much more comprehensive one, which contains many supplementary experiments.
Two new PowerPoint presentations to the topics “Teaching Entropy with Fun” and “The “Secrets” of Mixtures” can be found from now on under “teaching materials”.
May 2020

On the other hand, two methods for measuring reaction rates are also presented (16.7 and 16.8). But catalysis is not neglected either, with an example from enzyme kinetics (19.4). Have fun with the experiments!
